The package includes the latest version of the OpenStack cloud-hosting software, called Icehouse, due to be released Thursday.
This is notable in that OpenStack itself will only support each release through the next two releases, a duration that has been until now about 18 months.
Ubuntu 14.04 is also the first to include Docker,a Linux container technology that provides a lighter-weight alternative to running full virtual machines.
This is also the first edition to include XFS, a high performance 64-bit journaling file system first developed by SGI (Silicon Graphics). Canonical competitor Red Hat plans to use XFS as the default file system for the next edition of its Red Hat Enterprise Linux (RHEL) distribution.
Red Hat also includes Docker and OpenStack in RHEL.
Canonical has also equipped Ubuntu to work more effectively with solid-state disks (SSDs). Ubuntu 14.04 comes with Linux kernel version 3.13, released in January. Linux 3.13 includes a new technology called Multi-Queue Block Layer, which improves read-write performance on SSD disks by spreading the work across multiple cores.
